Dolly Unleashes Torrential Rain, Brings Flood Risk to Mexico

September 4, 2014; 4:31 AM ET

Dolly made landfall just south of Tampico, Mexico Tuesday night and will continue as a tropical rainstorm over northeastern Mexico through the middle of the week.

While seas and surf will diminish beyond Wednesday, torrential rainfall will continue over northeastern Mexico into Thursday and Friday.

Further interaction with land and increasing mountainous terrain will cause Dolly to break up, but moisture will continue to drift northwestward.

Kottlowski warns that the system will bring the risk of life threatening flash flooding and mudslides in the foothills and higher terrain of the Sierra Madre Oriental Mountains, regardless of how strong the system is.

More than a foot of rain can fall on the foothills and mountains in the Mexico states of Tamaulipas, San Luis Potosi, Hildalgo and Nuevo Leon.

Major cities in Mexico that can be affected include Monterrey, Ciudad Victoria, Tampico and La Pesca.

The Texas cities of Brownsville, McAllen, Harlingen and Laredo will also capture some of Dolly's drenching rainfall. Spotty showers and thunderstorms will reach as far to the north as Del Rio, Corpus Christi and San Antonio, Texas.
